The spinal dural arteriovenous fistula is a common vascular malformation with unclear etiology and unspecific clinical presentations.An early diagnosis is important for the treatment,therefore the authors reviewed and comprehanded the pathology,diagnosis and treatment of this AVM.

Objective To evaluate the treatment of spinal cord vascular malformations by endo vascular therapy. Methods All 41 patients including 3 cases were embolized by 3 0 silk line segments, 14 cases by selective embolization of dry dura particles, 16 by PVA and 8 cases by NBCA. Results Lesions were completely embolized in 27 cases, and partialy embolized in 14 cases. Paralysis of limbs were significantly improved in 36 cases, the other 5 cases showed no improvement on account of previous resection of the lesions. During 32 months follow up period, 18 cases recovered completely but with recurrence in 5. Conclusion Endovascular therapy is effective for spinal cord vascular malformations.

90%) in 57, 70%-90% in 27 cases, 50～70% in 8 cases,

Objective To evaluate the efficacy of embolization for spinal intramedullary arteriovenous malformations.Methods 25 patients with spinal intramedullary arteriovenous malformations (AVMs) were reviewed. Embolic therapy was conducted in 4 patients by introducing the tip of a catheter into the segmental arteries and injecting lyophilized dura or polyvinyl alcohol(PVA). Microcatheter were navigated into the feeding arteries and injected PVA in 9 patients, and NBCA in 7 patients. Embosphere was used after embolizing an aneurysm in the feeding artery with NBCA in one pateint. Results Spinal angiography immediately after embolization disclosed that the lesion were obliterated almost entirely in 12 cases and partially in others. The anterior or posterior spinal artery was preserved in all patients recently. The clinical follow-up period after embolization ranged from 6 to 60 months. 16 patients improved but four patients did not show any improvement.Conclusions Embolization appears to be the treatment of first choice in the management of juvenile or partial glomus AVMs which are not amenable to surgery.

This paper reports 17 cases of traumatic bilateral epidural hematomas. The incidence of these cases was 8.7% of all cases of epidural hematoma. The hematomas in 15 cases were across the midline, and in the other 2 cases were at different location on either side. The mechanism and clinical features of bilateral epidural hematomas were discussed. The indications for early diagnosis were stressed.

ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease （NAFLD） in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site， and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019， 2020， and 2021， and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups， and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD， and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD； the area under the ROC curve （AUC） was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years， the incidence rate of NAFLD was 9.4% （992/10 597） among the study population. After adjustment for multiple factors， there was a significant increase in the risk of NAFLD with the increase in ZJU index， with a hazard ratio of 2.55 （95% confidence interval ［CI］： 1.60‍ — ‍4.06）， 7.32 （95%CI： 4.78‍ — ‍11.20）， and 21.74 （95%CI： 14.32‍ — ‍33.00）， respectively （all P_trend<0.001）. The ROC curve showed that ZJU index had a higher value in predicting NAFLD （AUC=0.816）， and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup （AUC： 0.829 vs 0.809）. ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.
